HIGH 8.8UPGRADE
CVE-2026-17346 is a high-severity flaw (CVSS 8.8) affecting pgadmin 4. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.
The fix for CVE-2026-12044 in pgAdmin 4 9.16 hardened qtLiteral and switched sixteen COMMENT ON / pgstattuple / pgstatindex templates to it, but missed several sinks that had been placed in test_sql_string_literal_lint.py's ALLOWLIST on the incorrect assumption that schema, table, publication, and subscription names sourced from pg_catalog via the browser tree could never contain an apostrophe. PostgreSQL permits arbitrary characters in quoted id
Why this priority
- High severity
A fixed release or distro patch exists.

pgadmin pgadmin 4 UPGRADE
Affected: >= 1.0 and < 9.17
Fixed in: 9.17
Safe to downgrade to: a release before 1.0
1. Check installed version
apt-cache policy pgadmin-4 || rpm -q pgadmin-4 || pgadmin-4 --version
2. UPGRADE to 9.17 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade pgadmin-4
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade pgadmin-4
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 1.0 (Debian / Ubuntu)
apt-cache madison pgadmin-4
sudo apt install pgadmin-4=<VERSION_BEFORE_1.0>
sudo apt-mark hold pgadmin-4
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list pgadmin-4
sudo dnf downgrade pgadmin-4-<VERSION_BEFORE_1.0>
sudo dnf versionlock add pgadmin-4
Downgrade risk
Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.
After downgrade
Restart the service, and keep the package held until a fixed release ships.
